WebFor example, a person may have a balanced translocation between chromosomes 7 and 21. The q arms of each chromosome have been switched. But this person has all the genetic material required... WebThe most common example is a Robertosonian translocation, which results when two acrocentric chromosomes (chromosomes with arms of unequal lengths due to a non-centered centromere) lose the short arms of the chromosomes, and the two long arms consequently conjoin. Robertsonian translocations are one potential cause of trisomies.
WebChromosomes are structures that look like thread, which live in the nucleus (center) of cells. One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus. Without these, our chromosomes would be as tall as we are! WebCells and organisms with pairs of homologous chromosomes are called diploid. From Wikipedia They are diploid, i.e. containing both pairs of homologous chromosomes. From Wikipedia Meiosis is distinct from mitosis in that a central feature of meiosis is the alignment of homologous chromosomes followed by recombination between them. From Wikipedia
WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ... WebDec 14, 2024 · A human male has two sex chromosomes, the X and the Y. Unlike the 44 autosomes (non-sex chromosomes), the X and Y don’t carry the same genes and aren’t considered homologous. Instead of an X and a Y, a human female has two X chromosomes. These X chromosomes do form a bona fide homologous pair.
